This recipe is ok. I added 1tsp of vanilla extract because I did not see much flavoring in the cookie. Like the other reviewer, I only got 22 cookies. Not sure how to get to 30 cookies. They must be pretty small. One tip: Refrigerate the dough for 15-20 min and roll the dough into balls to achieve a beautiful smooth domed cookie.
Quick, easy and delicious. Only got 21 cookies out of it, not 30. Will double for next time.
